Domains & DNS

Vendor-neutral DNS fundamentals for MSP techs.

Domains and DNS sit underneath almost every customer ticket: web isn't loading, email won't send, the verification step won't go through. This track takes you from 'I don't really know DNS' to 'I can reason about any DNS change before I make it'. Record types, registrars, mail authentication, propagation, transfers, and the change requests that look harmless but aren't.

VoIP fundamentals

Vendor-neutral SIP, RTP, and call-diagnostic skills for MSP techs.

SIP signalling and RTP media sit underneath every voice ticket. This track takes a tech from 'I don't quite know how VoIP works' to 'I can read a packet capture and tell you why this call failed'. SIP handshakes, SDP and codec negotiation, NAT traversal, Wireshark call-flow diagnostics, and the failure modes you'll see in the field.
